Wtf? Why did I like this?

Have you ever thought "I wonder what it would be like to become a shapeshifter so my body could accommodate increasingly larger monster schlongs and have free access to multiple supernatural species to handpick for my own personally designed orgies?"

No? Me either. Until now.

Cat lives an unful"filled"ife with these basic human schlongs. So when she is given an offer she can't refuse in the name of "Science!" she jumps head first into the opportunity. She is VERY eager to "test" each and every monster and can be very vocal and demanding. *You go Glen CoCo*

This book is 90% Smut. 10% story. And 125% "WTF did I just read?"

Read it. Just Do it. Someone else needs the image of a Centaur schlong going quite literally in one end and out the other, without killing anyone. YOU'RE WELCOME.

Science, Monsters, and Zero Respect for Anatomy.

Test Subject is easily one of the most ridiculous, entertaining things I’ve ever read, and Tami (the author) is genuinely hysterical. Her humor is so sharp and unhinged that I kept laughing mid-chapter like, “There’s no way she actually wrote that… oh wait. She did.” ("I feel like more cum than girl" is a personal fav lol)

The pacing? Impeccable chaos. Every door Kat opens is a new “surprise biology lesson,” and you truly never know what creature is waiting on the other side. The escalation is insane.

The final boss structure is honestly brilliant: she has to go in order because her body literally cannot handle skipping levels. Door 1 preps her for Door 2, which preps her for Door 3… all the way up to the Big Bad at Door 10. It’s like a monster-sex training regimen. Progression-based peril. I respect the vision.

And Kat is just out here doing her job like a pro. Clipboard in hand. Safety protocols ignored. Body being bent, stretched, and shape-shifted into configurations that aren't medically recognized (what do you mean she's being impaled and loving it?). Yet she stays committed to the work and making a difference.

In short:
If you want something funny, fast-paced, a little feral, and unlike anything you’ve ever read - this is your book.

Whichever angle you look at this, it's fucked up - but yea it did cure my inability to read a line.
There was smut with just anything; a dhinni, a dragon, a werewolf, a pixie, a minotaur, a monster jellyfish, A STONEMAN, 🐲🧞🗿🐙🐺

I haven't read a single line for the past two weeks with how swamped up I am with my studies and job.

So yea, this is a wild read. Excuse me while I go find out, how a scientist who was supposed to draw out blood from 10 mythical creatures, but end up having the smuttiest sex WITH ALL OF THEM..

Monsters and spice? What more does one need?

When I started, I had no clue as to where this story would end up. The writing and characters kept me engaged.

There is a plot to go along with the spice so for those that need story, it's got you.

I was reluctant to start this originally but eventually, after seeing so many others talking about it, I broke down and read it.

No regrets.

Read it!!!!

This Is one of the best off the wall smut I’ve read in a while. The writer is insane! How did she even think about 90% of this stuff! I couldn’t imagine half! The creativity knows no bounds. It’s a very good read if you’re into taboo, monsters, magic and sexy time 😮‍💨!

The writer wasted no time and jumped right into the plot! 10/10 HIGHLY RECOMMEND!

Read this book for shits and giggles since I had already installed the app for another story.

This is one of the most ridiculous stories I have ever read, but for some reason I kept reading because I too was curious what kind of insanity would be behind the next door.

The writing wasn’t great, plot was very predictable and basically kept repeating itself. But it was short and was fine to kill some time.

3.5⭐️

This one was… interesting. For lack of a better word. Definitely worth the read. I really enjoyed most of the smut except for that one wtf moment. If you read this I’m sure you know exactly what I’m talking about.

this book was absolutely ridiculous, but why did i kinda like it… this lady scientist gets a new job fucking monsters to collect their semen to hopefully procreate a new species that’s becoming extinct? under the guise of collecting blood samples by her boss, she goes into each cell and gets fucked by a werewolf, centaur, ogres, pixies, djinn, A ROCK, and a dragon… this made me laugh so much and i loved it. truly a ridiculous masterpiece. it was so cute when she made des have everybody live in the extra magical door bc she understood was lazarus said by “it’s a prison”. she’s now a dragon mom and essentially has an eternal life to procreate more dragon babies with des. this was lowkey so cute except for that scene where she almost died by that water blob, but hey 🤷🏼‍♀️ at least des had his hero moment and killed it.

hot and erotic

Couldn’t put it down. The storyline is great and the relationships even better. Must read. Absolutely worth the read. I’m sure I’ll read again.

The definition of monster smut - this is 1% plot and 99% massive penises. This book has made me realise one can ALWAYS be MORE imaginative - for example, there’s a chapter called “The Impaling” and I cannot over-emphasise how literal this title is. Unapologetically I would read this again 😂

4 UNHINGED, WEIRD, MONSTER SMUT ✨

I knew this was going to be crazy but I was actually shocked at some parts. 😳🫣🤣 I’m still not sure how I feel because my brain is trying to wrap itself around the crazyness that I just read. It was weirdly arousing, wildly creative, a little cringe 😬 from some of the things she had to do/ endure, and very very wet. Like monster fluids galore!

It’s just the type of weird crazy stuff I love to read bc it’s so outlandish that it’s genius! I mean…it’s basically the most unhinged depraved prepping process ever 🤣

I feel like more thought went into this than people think. Like the way the FMC had to adjust on a dime to communicate with each subject, the logistics of the anatomies…👏🏼👏🏼

It made a lasting impresssion so for that, 4 fold stars!

What a spicy 🥵 ride this book took me on!!! This was absolutely nonstop from the beginning to the end. I only wish the second book was available on Amazon. This was my first monster read and boy did it not let me down. It left me absolutely speechless. I figured Door 10 out as soon as I started reading it but I was giddy with the anticipation to find out what happened. I was not disappointed!! If you like your Novellas scorching hot this is definitely the read for you!!

eterogeneo, ma non in senso buono.
stile schizofrenico, ho smesso di farmi domande dopo le prime righe.
ogni capitolo lascia la sensazione che manchi sempre qualcosa, soprattutto una ragione per esistere.

Monster smut 🫣

One thing I will say though is why does the FMC keep saying her tongue was hanging out of her mouth? All I picture is her like a dog with their tongue out 🤣🤣 not sexy.

This book is wild but boy it hit the spot 🤭 I’m usually a dark romance girl so this was actually my first monster romance and I figured, “why not, let’s see which monsters I’m into”… well goddamn 😏 I learnt some things about myself.

💦 Thoroughly enjoyed it! 💦

If you’re looking for plot or story, this one ain’t for you 😂 But I did find myself surprisingly attached to some of the characters and I’ve already started book 2 🤪

If you need a good hit of smut, look no further 😜
